The Liars deal with Ali's lie. Ali's big kidnapping lie will continue to play a major role in the Liars' lives. As the official synopsis explains, "Now being forced to live through Ali’s latest lie, Aria, Emily, Hanna and Spencer try to cover their tracks, while simultaneously trying to piece together what happened in New York."

Is Jason guilty? In this sneak peek, the Liars debate who killed Mrs. DiLaurentis. Hanna and Emily are convinced it's Jason, but Spencer sticks up for her half bro. We know Spencer and Emily go on to "try to find out the truth about Jason and his whereabouts the night they were in New York." Having one person who is anti-Jason and one person who is pro-Jason on this investigation should make for a fun dynamic.

Who will talk to Ezra? In that same sneak peek, Spencer points out that someone needs to check in with Ezra to make sure he'll back up their lie, and Aria says she won't do it. Yeah, right. We know Aria has a scene with Ezra in Episode 4, and the synopsis for Episode 3 says that "Hanna and Aria have to close loose ends with the two people who know the truth about Ali’s story — Mona and Ezra." Since we can't really see Hanna buddying up to Ezra, we think that Aria will check in with her former boyfriend, while Hanna will probably try to appeal to her former BFF.

Hanna's identity crisis. Speaking of Hanna, the synopsis also says that "Hanna starts to examine who she really is — Hefty Hanna or Queen Bee Hanna — now that Ali is back." The answer might be "neither," since we know she eventually gets a darker, grungier style makeover.

Mrs. D's funeral. Based on the promo photos and the fact that Mrs. D's funeral is mentioned in that sneak peek, it looks like the funeral will take place this week.

The Liars are back in school. As you can see in the sneak peek above, the Liars are back in school (though Ali is not; she doesn't come back until Episode 5), and in this second sneak peek we see that Principal Hackett isn't going easy on them. "As I told your parents, the school will protect you from the press and the curious,” he tells them. “But there are limits to what we can do with these unusual circumstances. I need to know that you will do your part to keep the disruptions to a minimum.” How... supportive.
